Abstract:
Provided is a dual-head bolt, which is configured to be between an electric motor (100) and a mounting platform (200), and comprises a bolt main body (300) and a lifting ring (400). The lifting ring (400) is fixedly arranged on the bolt main body (300), an upper surface of the lifting platform (200) is arranged with a plurality of first connection holes (210), one end of the electric motor (100) close to the mounting platform (200) is arranged with a plurality of second connection holes (110), and the plurality of first connection holes (210) correspond to the plurality of second connection holes (110) in a one-to-one manner. Two ends of the bolt main body (300) are respectively connected to the first connection holes (210) and the second connection holes (110), one end of the lifting ring (400) abuts against a bottom end of the electric motor (100), and the bolt main body (300) is configured to rotate relative to the first connection holes (210), so that the electric motor (100) is away from the mounting platform (200). The technical problem in the art that intake and exhaust valves of a piston type air compressor are difficult to be disassembled so as to easily cause device damage and personnel injury is alleviated.
